What is a handling exoskeleton?
On the Maltese islands, where a significant share of the workforce is employed in warehousing, freeport operations and light manufacturing, the physical toll of repetitive handling is a familiar reality. Malta's compact industrial zones, from the Ħal Far industrial estate to the Marsa warehouses, host thousands of operators who lift, bend and carry throughout their shifts. The handling exoskeleton has emerged as a concrete answer to these daily demands, offering mechanical support where the body alone struggles to keep pace.
Definition and operating principle
A handling exoskeleton is a portable mechanical structure, worn directly on the operator's body, that assists movement during physical tasks. Unlike a simple harness or a lumbar belt, it acts actively or passively on the body's biomechanics to reduce the strain on joints and the spine.
The aim is twofold: to reduce biomechanical strain (lower back effort, shoulder tension, prolonged postures) and to enable the operator to work for longer, with less fatigue and a lower risk of injury. Operation relies on different mechanisms depending on the type of device: springs, counterweights, actuators, sensors or motors. Some models detect the user's movement to adjust assistance in real time.
The different types of exoskeletons
There are mainly three families of exoskeletons, each meeting specific needs:
- Passive exoskeleton: it uses springs, flexible blades or counterweights to return part of the energy generated by movement. No external power source is required. This is the most widespread solution in industrial settings, as it is lightweight, self-contained and free from battery constraints.
- Active exoskeleton: motorised, it actively assists movement using actuators and sensors. More powerful, it is also heavier, more expensive and requires a power supply. It is found more often in rehabilitation contexts or for very specific tasks.
- Semi-active exoskeleton: it combines both approaches to offer a compromise between weight, autonomy and level of assistance. This type is gradually developing in industry.
Applications vary depending on the design: carrying heavy loads, maintaining static postures (arms raised, bent-over work), or repeated kneeling work.
Lumbar exoskeleton vs load-carrying exoskeleton
The choice between a lumbar exoskeleton and a model dedicated to load carrying depends directly on the nature of the tasks to be performed.
The lumbar exoskeleton targets trunk flexion efforts. It is particularly suited to situations of repetitive handling where the operator regularly bends down to pick up or set down parcels. By reducing spinal compression, it limits the risk of lower back pain.
The load-carrying exoskeleton, meanwhile, supports the arms and shoulders during frequent lifting or holding loads at arm's length. It relieves the deltoids and trapezius muscles, which are often severely tested in logistics roles.
To choose, ask yourself the right questions: how frequent are the movements? What weight is being handled? What is the range of motion? An order-picking station will not call for the same solution as an assembly line with prolonged static postures.
Why adopt an exoskeleton in logistics and industry?
Reduction of musculoskeletal disorders (MSDs)
The figures speak for themselves: MSDs represent a substantial share of recognised occupational conditions across Europe, and Malta is no exception. Lower back pain, tendinitis, rotator cuff syndrome… These conditions are costly for companies, both in terms of sick leave and disruption to teams.
Studies carried out on passive exoskeletons show a reduction in lower back effort of up to 40% depending on the model and the tasks. In practice, this means less compression on the intervertebral discs, less muscle tension and, ultimately, fewer declarations of occupational disease.
Improved productivity and quality of working life
A less tired operator is a more enduring operator. In repetitive roles, the exoskeleton helps maintain a stable work rate throughout the day, without the usual drop in performance towards the end of a shift. The result: fewer improvised micro-breaks, fewer stops to recover, and an overall rise in productivity.
Beyond the figures, the impact on how teams feel is significant. Equipped operators report a reduction in pain and fatigue, which improves job satisfaction and encourages retention. In Malta's tight labour market, where competition for skilled warehouse and production staff is fierce, this point is far from trivial.
Integration into a QWL/CSR approach
Adopting a handling exoskeleton fits naturally into a Quality of Working Life (QWL) and Corporate Social Responsibility (CSR) policy. It is a practical response to obligations regarding the prevention of occupational risks, but also a strong signal sent to employees: their health matters.
The exoskeleton does not replace ergonomic adjustments or job rotation. It complements them, providing additional protection where other levers reach their limits.
How to choose the right handling exoskeleton?
Analysing needs and tasks
First and foremost, the critical movements must be mapped out precisely. Which movements generate the most strain? Is it load carrying, repeated bending, static postures? What is the frequency and duration of these tasks? The working environment also counts: available space, ambient temperature, wearing of PPE (helmet, gloves, safety shoes). In Malta, the summer heat and humidity add an extra layer of consideration when selecting a wearable device.
Technical and morphological criteria
The weight of the exoskeleton is a decisive criterion. The lighter it is, the less strain it adds to the operator. Range of motion and joint freedom must be preserved so as not to hinder natural movements. Morphological adjustments (height, build, laterality) are essential to guarantee a personalised fit. Finally, check compatibility with work clothing and personal protective equipment already in use.
Assessing return on investment (ROI)
The purchase cost of a handling exoskeleton ranges from €3,000 to over €10,000 depending on the technology. Added to this are ancillary costs: training, maintenance, trial phase. But the gains can be rapid: reduced absenteeism, increased productivity, fewer workplace accidents.
In many cases, a passive exoskeleton pays for itself in less than 12 months. An ROI of 12 to 24 months is common, making it a strategic investment rather than a mere expense.
Testing and involving operators
No deployment should take place without a pilot phase. Testing the exoskeleton on site, with the operators concerned, makes it possible to validate acceptability and fine-tune the settings. Training in use and adjustments is essential. Monitoring feedback then makes it possible to refine the deployment and extend the solution to the most relevant roles.
Regulatory and standards aspects
Legal framework in Malta and the EU
Under Maltese law, particularly the Occupational Health and Safety Authority Act and its subsidiary legislation, the employer is obliged to assess occupational risks and put in place appropriate prevention measures. The exoskeleton can be considered as personal protective equipment (PPE) within the meaning of the relevant EU directive, which entails obligations regarding compliance, training and informing workers.
The ISO 18646 standard defines methods for evaluating exoskeleton performance. It makes it possible to compare models objectively and verify their suitability for the identified needs.
Risk assessment and integration
The integration of an exoskeleton must be accompanied by an update to the workplace risk assessment. It is recommended to involve the relevant employee representatives and prevention officers from the reflection stage onwards. Also check compatibility with other PPE and the specific constraints of your working environment.
Examples of applications and feedback
Concrete cases in warehouses and logistics
In order picking, lumbar exoskeletons reduce fatigue and pain at the end of a shift. When unloading lorries at the Malta Freeport or in Marsa's distribution hubs, load-carrying models assist with lifting heavy parcels. On production lines, posture-support exoskeletons make it possible to work with arms raised without muscular exhaustion.
Testimonials and measured benefits
Companies that have deployed exoskeletons report a reduction in reported MSDs of 30 to 50%, an improvement in how operators feel and productivity gains of 10 to 20% on certain tasks. These results vary depending on the context, but the trend is consistent.
